The face of the king only betrayed nothing; he was cold, quiet, indifferent. Barbarina felt the blood mount to her cheek, and then retreat to her heart; she felt that it was impossible for her to preserve her self-control; she could not bear this cruel comparison of the portrait and the original, but she swore to herself that the king should not have the triumph of seeing her once more sink insensible at his feet; his proud, cold heart should not witness the outbreak of her scorn and wounded vanity. But her body was less strong than her spirit--her foot gave way, she tottered, and turned deadly pale. The king sprang forward, and asked in a sympathetic and trembling voice why she was so pale; he himself placed a chair for her, and besought her to rest. She thanked him with a soft smile, and declared she had better return home. Would the king allow her to withdraw? A cloud passed over Frederick's face; a dark, stern glance rested upon Barbarina. "No!" said he, almost harshly; "you must remain here, we have business with each other. Swartz has brought me your contract to sign; it requires some changes, and I should have sent for you if accident had not brought you here." "Your majesty can command me," said Barbarina. "We have business and contracts to consider," said the king roughly, "and we will speak of them alone. Go, Pesne, and say to Swartz I await him." Frederick nodded to the painter, and, seizing Barbarina's hand, led her into the adjoining room, his Tusculum, never before profaned by a woman's foot; open only to the king's dearest, most trusted friends. CHAPTER XV. THE CONFESSION. Barbarina entered this room with peculiar feelings; her heart trembled, her pulses beat quickly. She, whose glance was usually so proud, so victorious, looked up now timidly, almost fearfully, to the king. He had never appeared to her so handsome, so imposing as in this moment. Silently she took her place upon the divan to which he led her. Frederick seated himself directly in front of her. "This is the second time," said the king, with a smile, a the second time, signora, that I have had the honor to be alone with you. On the first occasion you swore to me that you would hate the King of Prussia with an everlasting hatred." "I said that to your majesty when I did not recognize you," said Barbarina. "Had you known me, signora, you would surely not have spoken so frankly. Unhappily, the world has silently resolved never to speak the truth to kings. You avowed your resolution, therefore, at that time, because you did not know you were speaking to the king. Oh, signora, I have not forgotten your words. I know that you pray to God every day; not for your own happiness, as all chance of that has been destroyed by this cruel king; but for revenge on this man, who has no heart, and treads the hearts of other men under his feet." "Your majesty is cruel," whispered Barbarina.
